Blockchain solves warming---investors are key to innovation.

Blockchain is a powerful tool that can significantly improve the transparency, accountability and traceability of greenhouse gas emissions. It helps companies provide more accurate, reliable, standardised, and readily available data on carbon emissions. Blockchain can be utilised through smart contracts to better calculate, track and report on the reduction of the carbon footprint across the entire value chain. It can provide instant authentication, verification of real-time data and clear data records. Blockchain technologies can transform individual efforts of companies into a networked effort. And, it can clearly pinpoint the contributions individual actors make to reduce their carbon footprint. The spirit of competition and market-based incentives create a win-win situation for all. Clean technology startups play a critical role in this process. They develop blockchain-enabled platforms that bring together all stakeholders, including companies, government and citizens. The decentralised approach of blockchain provides both breadth and depth. It engages and enables everyone to participate in the calculation. It allows for tracking and reporting of reductions in greenhouse gas emissions along the entire supply chain, including manufactures, suppliers, distributors and consumers. Innovations in blockchain technologies are powerful enablers for collective action to fight climate change. Recognising the unique value of clean technology startups in this process is of great importance. Public and private investors are starting to take notice of their unique value.
